I will post a pic of my "custom" fx40s. My friend makes custom fitted high end iems and took impressions of my ear and gave me a pair of molds that I can just stick any normal iem driver tube into with the housing outside of the mold. Makes a pretty perfect seal. I would think my bass response is a bit better due to this. Also, they go as deep into the canal as possible without causing damage. Pretty neat. B/c you can swap out any iem you have easily and they are super, duper comfortable.

while i like the idea im not so sure on it, i spoke to an audiologist about this and with dynamics sound being related to the enclosure they come in its pretty much hit or miss. Good for some experimenting though and im interested in seeing the pics and your def right it doesn't get any comfier than customs, although i find myself leaving them a lot more recently due to so many good dynamics being around.

hmmmm not sure if this has been asked/ addressed or not, but regarding the sound of the Tt isurus to the CKM500s, how many % do the Tt's have on the 500s? Since I remember that Dsnuts guesstimated that those could have been a ATH re-brand. Can those that have both sets chime in or do a quick A/B between them?

The reason I am asking this is because eventually I'll get the CKM500s as part of my collection, but the sound of the Tt's are so lackluster that I don't want to be disappointed if the 500s are very similar in sound. Yet again the FX40's are at fault for bringing the Tts to shame even though I only paid $10 for them. Dunno, was never really impressed by the Tts as Dsnuts was, but researching about them led me to this thread and lets just say was truly inspired by Dsnuts fanaticism.... cough... cough... "passion" for this hobby of his, so they served their role I guess. Maybe this was all meant to be haha.

That didn't conclude that burn-in was real, it concluded that 2 pairs of Q701 sounded different. It's easy to believe a factory will release 2 models of the same headphones with audible differences, and they do. However 2 other tests he did showed a variation of about 0.5dB, so not exactly "OMG these are soooo much better"-worthy. Burn-in exists and we probably can't tell.

I believe the pads have more of an effect on burn-in.

Quick question, which of the budget JVC IEMs come with carrying cases? I didn't see any on the FX40 or FX101.
